Question

Solve and find out the positive value of the variable.

3-x²/8+x² = -3/4​

Answer 1

Answer:

x=6

Step-by-step explanation:

$\frac{3 - {x}^{2} }{8 + {x}^{2} } = \frac{ - 3}{4} \\ - 3(8 + {x}^{2} ) = 4(3 - {x}^{2} ) \\ (- 24 + {x}^{2} ) = (12 - {x}^{2} ) \\ (- 24 - 12) = {x}^{2} \\ ( - 36) = {x}^{2} \\ {x}^{2} = \sqrt{36} \\ x = 6$
